Experimental Study on Self Compacting Self Curing Concrete Using Copper Slag as Partial Replacement of Fine Aggregate

Self-Compacting Concrete has gained wide use for placement in congested reinforced concrete structures with difficult casting conditions while in Self Curing Concrete, water is restricted by means of some chemical compounds to move out from the concrete body. The main problem due to acute shortage and high price of river sand led to the enormous usage of M sand in construction. Use of copper slag as a fine aggregate is a good alternative to M sand and a better remedy to the disposal of copper slag. This investigation is aimed at utilizing the benefits of both self-compacting and self-curing concrete incorporating Copper Slag. In this study, the fresh and hardened properties of M50 equivalent Self-Compacting Concrete is obtained by incorporating 15% of Fly Ash as constant. Self-curing agent Polyethylene Glycol is added in 0, 0.5,1 and 1.5% to Self-compacting Concrete and its optimum is evaluated based on strength parameters. The optimum dosage of Copper Slag by the replacement of fine aggregate in different percentages of 10, 20, 30, 40 and 50% in Self-Compacting Self-Curing Concrete is obtained and their strength parameters are compared with normal Self Compacting Self-Curing Concrete. The utilization Fly Ash and Copper Slag which indirectly facilitate waste reduction helps in maintaining the ecological balance thus reduces the consumption of cement and aggregates.
